It's the same story with pretty much every injury- we won't have any idea how he's going to be until he's out there playing. He obviously has a lot of upside, but also has a lot of risk. If you have 10+ keepers, I'd certainly consider him, but it's just too risky if you only get to keep a few. I'd rather hold onto guys with less question marks, then maybe draft him later when more is know about his situation.
In terms of recovery time, they've said it varies with this injury, but it could be up to 12 months. Some people have had it and recovered in less than 6 months. There's a chance he starts from game 1, there's a chance he doesn't see the field next year at all. Most likely, somewhere in the middle.
